The syslog-ng 3.0 Administrator Guide

To upgrade the syslog-ng agent application on hosts that are not members of a domain, install the executable (.exe) version of the syslog-ng Agent for Windows installer and select Standalone mode. The installer automatically receives and converts every setting of version 2.1.x and 2.2beta, and continues to send the log messages to the configured destination. At the end of the installation, the new configuration interface is displayed, where you can start using the new features of the syslog-ng agent.

To upgrade the syslog-ng agent application on hosts that are members of a domain, install the executable (.exe) version of the syslog-ng Agent for Windows installer and select Manage syslog-ng Agent centrally using Group Policy. After that, the installer asks if you want to use the existing configuration as a Local Policy, or as a Group Policy. (Selecting both options is also possible, although seldom needed.)

If you decide to use it as a Group Policy, enter the unique name for the policy, or select it from the list of available policies. Any local settings are automatically added to the group policy, so these local settings will be applied to every computer that belongs to the selected group policy. Afterwards, the installer converts every setting of version 2.1.x and 2.2beta, and also automatically downloads any group policies that are configured on the domain controller.

	Warning
	If there are any group policies for the syslog-ng agent configured on the domain controller, downloading the group policies to the clients will overwrite the local settings.

	Note
	Upgrading from version 2.1 is supported for the 32-bit Windows XP and Server 2003 platforms.
